JumpRoACH, a robotic insect from SNU and UC Berkeley.

JumpRoACH Is a Robotic Bug That Leaps and Flips Just Like an Insect

In the quest for the most capable robotic bug (which is a quest that many roboticists seem to be on, because robotic bugs are nifty), some of the most exciting designs are inspired by the dynamic, multi-modal ways in which insects are conquering the world. Combining skills like running with skills like jumping can make little robots much more efficient movers, allowing them to go farther on a charge as well as helping them surmount obstacles and rough terrain.

Most of the small jumping robots we’ve seen before use a spring mechanism with a latch on it. The latch makes the spring state binary: the spring gets all wound up, the latch holds it, and then disengages on command, releasing all of the energy in the spring in one go. You can get a lot of power this way, but it’s an all or nothing sort of thing, so the magnitude (height, distance, whatever) isn’t controllable. 

At Seoul National University, South Korea, researchers have developed a new kind of jumping mechanism for robots that can potentially scale from itty bitty hops all the way up to aircraft carrier catapult launch (or almost). In collaboration with UC Berkeley, they’ve managed to stuff this thing into a familiar hexapedal crawler that we’re all familiar with (DASH), with the end result being a running, jumping robot called JumpRoACH that only weighs 60 grams but has an incredible 1.6 meters worth of hops.

Researchers Teaching Robots to Feel and React to Pain

One of the most useful things about robots is that they don’t feel pain. Because of this, we have no problem putting them to work in dangerous environments or having them perform tasks that range between slightly unpleasant and definitely fatal to a human. And yet, a pair of German researchers believes that, in some cases, feeling and reacting to pain might be a good capability for robots to have.

The researchers, from Leibniz University of Hannover, are developing an “artificial robot nervous system to teach robots how to feel pain” and quickly respond in order to avoid potential damage to their motors, gears, and electronics. They described the project last week at the IEEE International Conference on Robotics and Automation (ICRA) in Stockholm, Sweden, and we were there to ask them what in the name of Asimov they were thinking when they came up with this concept.

Video Friday: Whiskered Robot, Haptic Jamming, and Humorous Humanoid

ICRA is almost over, and we hope you’ve been enjoying our coverage, which so far has featured robot mothszipper actuators, machine learning, and duckies. We’ll have lots more from the conference over the next few weeks, but for you impatient types, we’re cramming Video Friday this week with a painstakingly curated selection of ICRA videos—emphasis on pain: there were over 400 videos!

We tried to include videos from many different areas of robotics: control, sensing, humanoids, actuators, exoskeletons, manipulators, prosthetics, aerial vehicles, grasping, AI, VR, haptics, vision, and microrobots. There’s even a cybernetic living tree that drives around on a mobile robotic base! We’re posting the abstracts along with the videos, but if you have any questions about these projects, let us know and we’ll get more details from the authors.

We’ll return to normal Video Friday next week. Have a great weekend everyone!

Watch-Bot robot from Cornell and Stanford

This Robot Uses Machine Learning to Take Care of Absent-Minded Humans

There are all kinds of apps that will remind you to do things, which is great, if you remember to ask them to remind you to do things. At ICRA yesterday, researchers from Cornell and Stanford presented a project called Watch-Bot, which can independently learn your household activity patterns to provide you with helpful reminders. If you leave the milk out, or forget to turn a monitor off, or leave food in the microwave, the robot will figure out on its own that you forgot to do something and then gently remind you.

With lasers.

Harvard robot moth

Harvard Launches Robot Moth

Harvard researchers have been working on their robot bee for a really, really long time (in robot years). It’s impressively small, being bee-sized, but it turns out that it’s so small that it’s not realistic to expect it to fly with onboard power and computing in the near future. Plus, the flight dynamics of tiny insects like bees is significantly different from larger insects like butterflies and moths, which exhibit combinations of flapping, gliding, and soaring flight. To explore this, Harvard researchers have developed FWMAV, a novel insect-scale flapping-wing micro-air vehicle that’s just small enough to be called “micro” and just big enough to operate completely untethered.

SoftBank Prepares Humanoid Robot Pepper's U.S. Debut, Releases Android SDK

Pepper is finally coming to America. Japanese telecommunications giant SoftBank said today that its chatty humanoid robot, unveiled with great fanfare by the company’s founder and CEO Masayoshi Son two years ago, is expected to debut in the North American market later this year. SoftBank also announced that a new developer portal is now available to anyone interested in creating applications for the robot. And tomorrow at Google I/O, SoftBank engineers will take the stage, along with Pepper, to introduce a tool that they hope will entice more developers to build apps for the robot: an SDK for the Android mobile operating system.

Spiral Zipper Creates Robot Arm Out of a Strip of Plastic

As useful as robot arms are, they tend to be heavy, bulky things that need a bunch of support and structure to get them to work properly. If you need precision and speed, this may be unavoidable, but if all you’re looking for is long reach, a high-strength to weight ratio, and very low cost (which, admittedly, are a lot of things to be looking for), another option was presented at ICRA today by researchers from the University of Pennsylvania: an arm made out of a strip of plastic that zips together with itself, creating an extendable cylinder that can be paired with winches and cables and used for manipulation.

Microspines Make It Easy for Drones to Perch on Walls and Ceilings

Morgan Pope is a PhD student investigating robots that live at the boundary of airborne and surface locomotion at Stanford’s Biomimetics and Dexterous Manipulation Lab. He wrote about SCAMP, a flying and perching robot, for Automaton earlier this year.

A disaster site. A rainforest. A battlefield. These places have something in common: we have a need to understand what’s going on where established infrastructure can’t give us good data. Advances in computation, fabrication, and materials over the last half-century have resulted in small, cheap, and lightweight sensors that can provide us with these data; now the task is to find ways to deploy such sensors rapidly and effectively.  

One way to do this is with small, agile aerial vehicles like quadrotors. Quadrotors are becoming affordable, ubiquitous platforms that can fly quickly over rugged terrain to collect critical data. There’s a catch, though: most small (less than 1 meter in diameter) quadrotors can only stay in the air for tens of minutes at a time, and this limited endurance makes some missions unachievable. However, if the goal is to collect data from a fixed vantage point, there is an alternative to hovering in place that might extend mission life from minutes to days or even  longer: perching.
